I've only been on these tires just at 2 months, but so far I love them. Previous tire was the Yokohama Avid Envigor, and while I mostly loved them, the road noise on many highway surfaces was murder. Very loud, high-pitched noise. ZERO noise with the Continentals.
Rain traction is great. Light snow traction is very nice. I have a set of Blizzaks on separate wheels, but it's nice to know I won't have to swap them on for 1-2 snowfalls.
Cornering is very confident, including spirited runs on clover-leaf freeway ramps. They do seem more responsive to steering input under load.
If these tires do well on wear, I can't see any reason I'll switch once these wear out.
